drm/i915/dp: workaround BIOS eDP bpp clamping issue
suddenly it is not.
Right now i found one more way to bring eDP up. After start i can open
gnome-control-center, display setting and press save. No changes needed. It
will reenable eDP. Output of xrnadr --verbose, before and after this action,
differs only here:
< CRTCs: 1 0 2
